Description Kathy Carroll CLA 2011-09-21 15:58:58 EDT 
I think all the variations should return works. 

program driver type BasicProgram {}
	function main()
		smallFloatn1 smallFloat? = 1.4028e6;
		floatn1 float? = 1.4028e56;
		
		if (smallFloatn1 isa smallfloat)
			syslib.writestdout("works");
		else
			syslib.writestdout("unexpected");
		end
		
		if (1.4028e6 isa smallfloat)
			syslib.writestdout("works");
		else
			syslib.writestdout("unexpected");
		end
		
		if (1.4028e6 isa float)
			syslib.writestdout("unexpected");
		else
			syslib.writestdout("works");
		end
	end
end

Hi Kathy,

This is actually working correctly.  We don't have a literal syntax for smallfloats.  1.4028e6 (and every literal number with an 'e' in it) is a float not a smallfloat.

You could change it to this: (1.4028e6 as smallfloat) isa smallfloat

-Matt
